Abstract & Overview
In psychosomatic medicine, a harmonious brain–body interaction is an important cornerstone of physical health. The modern brain–computer interface (BCI), an interaction between the brain and abiotic devices, provides the benefits for people with the help of powerful computers. Our newly proposed term brain–apparatus communication (BAC), acknowledges the unique value of the above two interactions and further describes their interdependence; how this interdependence permits a better understanding of physical and psychological health and promotes the harmonious coexistence of people with the environment is worth exploring. This perspective article provides a general review of the three types of interactions and discusses the possible future trends.
